Answer:
84%
Step-by-step explanation:
The area of the large rectangle is 10 × 5 = 50.
The area of the small rectangle is 4 × 2 = 8.
The area of the large rectangle that isn't shaded is 50 − 8 = 42.
The fraction of the large rectangle that isn't shaded is 42 / 50 = 0.84.
Therefore, there is a 84% probability that a point chosen inside the large rectangle is not in the shaded region.
